Title: Guidewire extension with self-latching detachable connector
Inventor: GAMBALE RICHARD A
IPC: A61M25/01
Filed: 1993-10-08
Abstract: GUIDEWIRE EXTENSION WITH SELF-LATCHING          DETACHABLE CONNECTOR             ABSTRACT OF THE DISCLOSURE     A guidewire system for use in catheter exchanges avoids the need for a separate exchange wire by connecting an extension wire to the proximal end of the guidewire thereby increasing the effective length of the guidewire to permit a catheter exchange.  The proximal end of the guidewire is attached to the distal end of the exchange wire by a disconnectible reattachable connection which avoids deformation of the connected joint.

Title: Method and apparatus for ablative processing of elastomeric products
Inventor: WILER DONNA M
IPC: B23K26/40
Filed: 1994-11-02
Abstract: A method and an apparatus for ablating selected surfaces of an elastomeric product or an attached work piece. A tire is positioned beneath a laser system such that a laser beam is cast upon the tire sidewall or applied work piece.

Title: System and method for in situ testing of the leak-tightness of a tubular member
Inventor: KEATING ROBERT F
IPC: G01M3/32
Filed: 1995-02-13
Abstract: System and method for in situ testing of the leak-tightness of a tubular member, which tubular member may be a nuclear steam generator heat transfer tube.  The system includes a mandrel insertable into the tube, the mandrel having a pair of spaced-apart expandable bladders surround-ing the mandrel.  A first channel extends through the mandrel and is in communication with the bladders.  A fluid supply circuit is in fluid communication with the first channel for supplying pressurized liquid to the bladders so that the bladders radially expand into sealing engagement with the inner diameter of the tube.   As the bladders expand into sealing engagement with the tube, a sealed annular chamber is defined therebetween bounded by the bladders and the inner diameter of the tube.   A second channel  also extends through the mandrel,  the  second channel being in fluid communication with the fluid supply circuit at one end thereof and in communication with the chamber at the other and thereof in order to pressurize the chamber with the liquid.  A controller is connected to the fluid supply circuit for measuring the flow rate of the liquid flowing through the fluid supply circuit to the chamber. Any crack in the tube wall adjacent the chamber will allow the liquid to escape therefrom at a characteris-tic flow rate corresponding to the size of the crack. However, the fluid supply circuit maintains the liquid pressure in the chamber so that the pressure and thus the liquid inventory in the chamber remains constant as the liquid leaks through the crack.  The controller, which is connected to the flow meter, measures the flow rate and pressure of the liquid flowing through the fluid supply circuit.  In view of the fact that the liquid (i.e., water) is incompressible, the flow rate through the crack and the pressure in the chamber are provided by measuring the flow rate and pressure of the liquid flowing through the fluid supply circuit.
